How to center the clock?

Hi,
I've just purchased and installed the module.

The only question is how to center the clock and without affecting the mobile view?

Here is our site.

---

.flip-clock-wrapper {
text-align: center; /*it doesn't seem to work*/
position: relative;
width: 100%; /*If I change the width, the mobile view will become weird and messy. */
margin: 1em;

---

Many thanks

Hi,

I would add something like this
margin-left: 33%;
and eventually different values based on screen width.
